Patented Sept. i0,

Application'led January 9, 1311. Serial No. 601,503.

6 State of New Jersey, have inven'ted certain newand useful Improvements in Dumping- Cars,.of which the following is a. iui, clear, and .exact specification.

, This invention relates to dumping cars,

10 and more particularly has reference to improvements whereby a plurality of car bodies can be simultaneously dumpedfrom a single .motor mounted on one of the'car .15 The invention isf' more especially applicable to what are known as cinder cars, which asheretofore constructed, have each had a dumping motor, and which have been c oupled together in'trains by ordinary coupling 20 devices', themotors being actuated usually by fluid' pressure.

, According to this invention, I propose to so conneet'two or more car bodies wit-l1 a singlepictuating motor in such manner that 25 this motor can simultaneously operate one or several 'ca-r bodies, and thereby save not only'the expense of providing each car body with its own "motor, but also to save time and labor in operating the cars.

'As herein shown;y the invention is applied to car bodies of the tilting andbodily movable type, wherein the body or ladle is supported in a yoke provided with trunnions which roll on trucks on the car frame, the

'35 .motor being. mounted on the frame and havingl its moving element conliected with one oi'. theftrunnions in a well known manner. The trnnnion opposite to the one connected to the motoris extended and provided with a 40 universal coupling which connects with the trunnion of the adjoining car body, and the ,number of car bodies so connected need only be limited by the power of the motor. The yeer'bodies themselves ere pivotally conellnected-by a -joint or coupling capable of horizontal motion to ,permit the cars to go Aaround curves, and also ai vertical movement 'of one car body `relatively to another so that they may ride over inequalities in the track a without straining the joint. The universal eonplng connecting the trunnions will therefore permit the motor to operate a plurality of car. bodies, even when not exactly in line.

stood in connection with the description of the accompanying drawings, wherein- Figure l is an elevation of a portion of, two cars embodying the invention; Fig. 2 is an elevation of the motor end of one car; Fig, 3 is a vertical section showing the connection between the car frames; Fig. 4l is an en'd elevation of one of the car frames showing the manner of supporting the body, and Fig- 5 is a detail view of the couplings tween the car bodies.

'il represents a car frame having pedestais 2, 2, having at one end a pivoted truck 3, preferably oiy standard railway type, sup-I porting the car fame in the usuel manner. At the other end of the frame is mounted a second truck 4, which carries he weightof the adjoining ends of two cars. The pochis-4 tals 2 are formed with trucks 5, on which roll trunnions carried by a yoke 7 which lat-ter supports the car body or ladle 8. Rigid with the t-runnions 6 are gear wheels 9, which roll on fixed racks 10 carried by the pedestals 2, and to one of the trunnions is attached the moving element of a motor cylinder 1l.

The motor cylinder and its actuating mechanism 4are unnecessary to be described herein specifically, being Substantially like that described in my Patent No. 928,837, dated July 20, 1909, or in accordance with other well known constructions, wherein fluid checking means muy be adapted for controlling the movements olf the car bodies. Suitable couplings will be provided at the forward end oi. the car to connect it to locomotive. At the rear end, the trunnion carries a universal coupling member le, which is Yconnected with a Similar member 16 carried by the trun-nions ein second csr body 17. The connection is made by a four armed cross or spider 2O which .has a sliding engagement with the respective coupling inembersll, 16. (See Fig. 5.) The pedestal of thesecond. carboldy is provided at one end with ,an overhanging portion 18 and Sphericalfproje'ction i9 which enga-ges in The .invention will bc more fully under- .1;

spherical depression in the end of 'pedestal 2 of car frame 1.

21 is a pin passing loosely through the end. 18 of carframe 17 and the end of car frame 1, and suitably bolted, there being suilicicnt play to allow the car frame 17 to swing vertically Without bending the pin 21, and to swing Y horizontally in ythe sphericalwdepression in the other car frame. The pin 21 is in verti- .cal alinement with the axis of the universal of the truck 4. It will be seen that the bolster 22 of the truck 4 can turn relatively to the end frame 2, as is the usual practice, and that the end 18 of the'second car can also turn relatively to thi'sibolster on the same vertical axis, and tberebuyT the truck 4. operates equally Well for botn bodies. Therear end of the frame 17 of the second car is shown in Fig. 4, and the body represented by 25, a second truck 4 being provided to support the rear end, and the yoke being .mounted on tracks and operated by rack and, gear in the same manner as before described.

,From the foregoing description it will be Seen that a number .of car bodies can thus be operated by a single motor, and thereby considerable expense saved, and also labor. Also, it will be seen 4that by providing a truck for supporting the ends of two cars simultaneously, there will be a. less number of trucks required to carry the same amount of Weight. In case it were desired to use only one ear, it will be seen that the motor car .is complete in itself, and that the other ca'r can easily be disconnected at the uni versal coupling by removing the bolt 21, and a casting adapted for ordinary couplers easily substituted.

It is thought that the nature and advantages of the invention Will-be fully understood from the foregoing description, and various changes and modifications Within the scope of the appended claims may be made without departing from the invention.

Having thus described my-invention, I declare that what l. claim as new and desire to secure by Letters Patent is,-

3. The combination with a plurality of separately supported tilting car bodies, of an actuatingVr motor connected to one cud of the tilting support of one of said car bodies, and a mechanical actuating coupling between the other cnd of said tilting sup port and one of the tilting supports of' an adjacent car body.
